This General Aire filter media consists of electrostatically charged synthetic material that dramatically reduces airborne particulates to provide healthier indoor air. These GeneralAir filters capture airborne particles down to 1.0 micron, and then traps them deep within the layers of spun-bonded fibers. The GeneralAire OptiFiber media is hydrophobic, so it does not absorb moisture. It is also resistant to shredding, assuring dependable and reliable dust-fighting capabilities.
